Perovskite BaCrO$_{3}$ cannot be stabilized in bulk but we have synthesized
this compound as a film. BaCrO$_{3}$ films have a substantially larger
lattice constant than other chromates, are insulating, and exhibit weak
ferromagnetism likely associated with canted antiferromagnetism. Comparison
with the sister compounds CaCrO$_{3}$ and SrCrO$_{3}$ suggests an anomalous
Mott transition caused by lattice expansion where magnetism is independent
of whether the compound is metallic or insulating.
